This game plays intervals for you to recognize by ear.

This is a fantastic game for improving your aural recognition of
intervals.

1. On the right, a tally is kept of your correct and incorrect answers
and game percentage.

2. Clicking the "Play Again" button does just that. If you didn't
recognize the interval the first time it was played, you can hear it
again as many times as you like.

3. If you change any settings, clicking the "New Interval" button will
make the new settings take effect immediately.

4. Clicking the "Direction" button determines whether the second
note of the interval is played higher (up arrow) or lower (down
arrow) than the first note OR higher or lower at random (up and
down arrow).

5. Pressing the "Play Mode" button determines whether the game
plays the notes separately, separately and then together, or only
together. (And the "Direction" selection you made in the previous
step will affect this setting as well!)
